Jadeveon Clowney draws attention everywhere he goes—on the field and off it.

Expected to be a top pick when he enters the NFL draft, the South Carolina defensive end is a target of autograph seekers and the university responded Wednesday to questions about Clowney-signed items showing up on eBay.

“We have investigated things that have been on eBay with him and student-athletes before,” associate athletics director Chris Rogers told GoGamecocks.com. “In the situations I can say we looked into, there was no further for us to go, and we determined there was no violation.”

Hundreds of signed Clowney items appear on sale on eBay, prompting questions in light of the news earlier this week regarding Texas A&M QB Johnny Manziel.

Manziel is reportedly being investigated by the NCAA after signing autographs for at least two autograph brokers who allege Manziel was paid for the signings.

It is not a violation for college athletes to sign items, but is if they are paid to do it.

“I have seen pictures of him in a hotel signing stuff before,” Rogers told GoGamecocks.com. “We are monitoring eBay regularly so any of those sorts of things that come, whether it’s autographed memorabilia, pictures of a student-athlete, whatever it might be, basically what we are trying to ascertain is, ‘Is there credible enough information to investigate further?’

“If you look up Jadeveon Clowney there are hundreds and hundreds of hits. We are trying to ascertain which of those are worth pursuing and which are not.”
